Subject: sparc: patch to fix parport_pc build on 32-bit

Hi Andreas,

Please pick up this patch from June/2023. I have already replied to
the patch with:

Acked-by: Randy Dunlap <[email protected]>
Tested-by: Randy Dunlap <[email protected]> # build-tested

and I just rechecked it on linux-next-20240223 to make sure that it
builds cleanly. It does; however, there is one trivial merge warning:

patching file arch/sparc/include/asm/parport.h
Hunk #1 succeeded at 20 (offset 1 line).
Hunk #2 succeeded at 252 (offset 1 line).

The patch:
https://lore.kernel.org/lkml/[email protected]/


Thank you.

I took a quick look at the patch. It does the minimal to fix the build
but the ebus_dma thing is only used by sparc64 an should not be visible
at all for sparc32.

I think the right fix is to make the current
arch/sparc/include/asm/parport.h sparc64 specific and use
asm-generic/parport.h for sparc32.

I posted a set of fixes here, including an updated parport fix.
